Batu Khan (l. 1205-1255 CE) was a grandson of Genghis Khan and the founder of the Golden Horde. Batu was a skilled Mongol military commander and won battles from China to Persia, although his most famous exploits involve the grand Mongol campaign into Europe from 1236-1241 CE which resulted in the Mongol horde annihilating the armies of Russia, Poland, and Hungary, among others. Later Batu would serve as the kingmaker of the Mongol Empire, effectively the most powerful man in the empire for a time.
